PERSONAL SAFETY PRECAUTIONS
1. Someone should be within range of your voice or close enough to come to your aid when
you work near a lead-acid battery.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or
eyes.
3. Wear complete eye protection, and clothing protection. Avoid touching eyes while working
near battery.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enter eyes, immediately flood eyes with running cold water for at least 10 minutes and get
medical attention immediately.
5. NEVER smoke or allow a spark or flame in vicinity of battery or engine.
6Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or
short circuit battery or other electrical part that may cause explosion.
7. Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with a lead-acid battery. A lead-acid battery can produce a short circuit current high
enough to weld a ring or the like to metal, causing a severe burn.
8. Use the charger for charging a LEAD-ACID battery only. It is not intended to supply power
to a low-voltage electrical system other than in a starter motor application. Do not use battery
charger for charging dry-cell batteries that are commonly used with home appliances. These
batteries may burst and cause injury to persons and damage to property.
9. NEVER charge a frozen battery.

OPERATING INSTRUCTRIONS
PREPARING TO CHARGE
a. If necessary to remove battery from vehicle to charge, always remove the grounded
terminal from battery first. Make sure all accessories in the vehicle are off, so as not to cause
an arc.
b. Be sure area around battery is well ventilated while battery is being charged. Gas can be
forcefully blown away by using a piece of cardboard or other non-metallic material as a fan.
c. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d. Add distilled water in each cell until battery acid reaches level specified by battery
manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery
without cell caps, carefully follow manufacturer's recharging instructions.
e. Study all the battery manufacturer's specific precautions such as removing or not
removing cell caps while charging and recommended rates of charge.
f. Determine voltage of battery by referring to car owner's manual and make sure that output
voltage is set at correct voltage. If charger has adjustable charge rate, charge battery initially
at lowest rate.
CHARGER LOCATION
a. Locate charger as far away from battery as output cables permit.
b. Never place charger directly above battery being charged; gases from battery will corrode
and damage charger.
c. Never allow battery acid to drip on charger when reading gravity or filling battery,
d. Do not operate charger in a closed-in area, or restrict ventilation in any way.
e. Do not set a battery on top of charger.
DC CONNECTION PRECAUTIONS
a. Connect and disconnect DC output clamps only after setting any charger switches to off
position and removing AC cord from electric outlet. Never allow clamps to touch each other.
b. Attach clamps to battery posts and twist or rock back and forth several times to make a
good connection. This tends to keep the clamps from slipping off terminals and helps to
reduce risk of sparking.

TROUBLESHOOTING ERROR CODES
CAUSEPROBLEM Solution
Bad
Battery
Bad Battery LED may light when
the battery voltage is less than
2V; or the battery has a faulty
condition such as open, shorted
cell or sulfated condition.
• Lack of AC input power
• Faulty connections to battery
terminals
• Wrong charge voltage selection
• Battery voltage too low
• Charging a very cold battery
• Make sure that the charger is plugged
into AV outlet and POWER LED is lit.
• Unplug the charger and check the
battery connection; ensure that there
is a good connection at the battery
terminal/post and/or vehicle chassis.
• Check that the correct charge voltage
was selected for the battery being
charged.
• Ensure enough charging time was
allowed to charge battery.
• If the battery to be charged is
extremely cold (in temperatures below
freezing 0℃/32℉), it will not accept a
high rate of charge, so the initial
charger rate will be slow. The rate of
charger will increase as the battery
warms. Never attempt to charge a
frozen battery.
Have the battery tested by a qualified
technician.
